Only played the beginning, so I'm not sure how vast the dungeon area is…but if "feels" like it'll be quite large and rewarding

I don't remember huge dungeons in Wizardry 8, but some very nice big outdoor areas. And other thing that I remember about Wizardry 8 is the long battles. It could easily take half an hour to end a fight, and in the end I sometimes could forget where I was. By the way, it has one of the greatest character development system in the RPG history I think.

I played Anvil of Dawn in 2010 (secretly in my office computer ) Very enjoyable game and it features huge dungeons with lots of puzzles (much like Eye of the Beholder games) and gives the player a little bit freedom to where to go next.

Although not a RPG Realms Of The Haunting is one of my favourite FPS/adventure games. It's nice to see another forum member mentioned this. By the way, you can play the game hi-res in Dosbox at decent speed, so I recommend it to everyone who hasn't played it yet.
